Wilkerson M42 - Manual

INSTALLATION
1.Purge downstream air line of oil.
2.Install the unit with the air flowing in the direction indicated by
the arrow on the body and/or the DP2 indicator.
3.A drain line with 1/2" NPT connection may be attached to the drain port if
desired. (The optional X02-04-FM0 external drain requires a 1/8" NPT
connection). Drain line should be 1/4" tubing or larger, as short as
possible, and crimp free.
4.Maximum inlet pressure and operating temperature ratings are:
units with DP2: 150 psig (10,3 bar) 150°F (66°C); units with DP3: 200 psig
(13,7 bar), 150°F (66°C); units without DP2 or DP3: 200 psig (13,7 bar),
175°F (80°C).
TYPICAL INSTALLATION (not to scale)
A. PREFILTER - It is recommended that a Wilkerson “B1” Element
coalescing prefilter (particle removal down to 1.0 micron; maximum
downstream remaining oil content 0.5 ppm/wt.) be installed upstream from
the high efficiency coalescer filter to prolong element life.
B. AIR DRYER - (Refrigerative or Desiccant). An air dryer is recommended
if water vapor condensation is a problem.
C. HIGH EFFICIENCY COALESCER FILTER - It is recommended that a
Wilkerson “C” element coalescer filter (particle removal down to 0.01
micron; maximum downstream remaining oil content 0.01 ppm/wt.) be
installed to protect the compressed air system from oil and particulate
contamination.
D. OIL VAPOR FILTER - The Type D element filter (maximum downstream
remaining oil content 0.003 ppm/wt.) is an adsorption type for removing oil
vapors, oil-associated odors, whether petroleum base or synthetic base,
and nearly 100% of any remaining solid contaminants.
E. DIFFERENTIAL PRESSURE INDICATOR/GAUGE - Maximum
recommended pressure drop across coalescing filters is 7 psi (0,5 bar).
This can be monitored by using the Wilkerson DP2 differential pressure
indicator (standard) or the DP3 differential pressure gauge (optional).
F. VALVE - Do not use a valve or shutoff device in conjunction
with a coalescing filter that will allow a momentary or surge pressure
drop greater than 50 psig (3,4 bar). To avoid high surges which can
either ruin the element or momentarily allow downstream contamination,
use a slow-opening type valve.
MAINTENANCE
1.The element operates effectively when it is saturated. The element's
useful life will end only when the DP2 pressure indicator is completely red
or when the DP3 reads 7 psi (0,5 bar). The element cannot be cleaned or
reused and must be replaced at the end of its useful life.
2. IF THE UNIT HAS A MANUAL DRAIN, DRAIN THE UNIT ONCE EVERY 8
HOURS MINIMUM. If the unit is equipped with an external automatic drain
clean the screen around the drain. Clean screen by blowing it off with an
air blow gun.
3.When the bowl becomes dirty, clean by wiping with a dry, clean cloth.
4.Before placing the unit in service, make sure that the bowl is properly
reinstalled, and securely bolted in place.
